XPLA 22V10 - User signature area of the 22V10

Description

Does the XCR22V10 have a user signature (UES) area?

Solution

The XCR22V10 does have a UES area. This is the primary reason that a JEDEC file size mismatch error occurs during programming when existing non-Xilinx 22V10 JEDECs are used. This error or warning may be ignored during programming. The 22V10 is fully JEDEC compatible with other 22V10s in a common package/footprint.
